SPECIFICATION forming part of Letters Patent No. 727,163, dated May 5, 1903.

Application filed April 10, 1902. Serial No. 102,296. (No model.)

To all whmn it may concern:

Be it known that I, FRANK LISTERMAN, of Newport, in the countyof Campbell and State of Kentucky, have invented certain new and useful Improvements in Portable Ovens; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertnins to make and use the same.

My invention relates to an improvement in portable ovens, and more particularly to an improved deflector and means for supporting the same in the oven, the object of the invention being to provide an improved deflector connected at its ends with the oven-lining or directly to the oven-body by means of wire bails and so shape the deflector as to protect the oven-front from the flame and intense heat.

WVith this object in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figures 1 and 2 are views in section,taken at right angles to each other, of an oven embodying my improvements. Fig. 3 is a view of the deflector detached.

1 represents the ordinary rectangular ovenbody, having the opening in its front 2 closed by a door 3 and provided with removable linings 4 in its end portion. These linings are preferably of corrugated metal to support trays 5 and are flan g ed at their edges to space the lining from the oven-body.

My improved deflector 6 comprises a plate of sheet metal,preferably dished or depressed centrally, as shown, and provided at its forward edge with a depending flange or lip 7, its lower edge located in close proximity to the front 2 of the oven to deflect the flame and intense heat'awayfrom the front and prevent defacement thereof by its exposure to the constant flame and heat. The ends of the deflector are rolled or seamed onto Wire bails 8, the ends of which latter are projected through holes in lining 4- and bent at right angles to secure them in place. thus be seen that the sole support of the deflector is the wire bails, that they offer no obstruction to the free passage of heat, are cheaply made and permit of rapid assembling of the parts, and can be fastened to the linings before the latter are inserted in the oven, and I have therefore produced a distinct improvement over all devices of this character heretofore known;

Various other slight changes might be made in the general form and arrangement of parts without departing from my invention, and

and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with an oven, of a removable lining in the oven a deflector, wire bails attached to said deflector, the ends of said bails projecting through openings in the lining.

2. The combination with an oven, of a removable lining in the oven, a deflector, wire. bails,the ends of the deflector rolled or seamed onto the bails and the ends of the bails projected through openingsin thelining and bent at an angle.

3. The combination with a portable oven, of a removable lining for the ends of the oven, a deflector having a depending lip at its forward edge to deflect the heat away from the oven-front,and wire bails connecting the ends of the deflector with the lining.

v In testimony whereof I-have signed this specification in the presence-0f two subscribing witnesses.

FRANK LISTERMAN.
